ABSTRACT:
A method for manufacturing a twisted yarn includes the step of removing two rovings from two separate supplies and passing each roving through a separate drawing device. From each roving a separate spun yarn is produced by ring-spinning. Each spun yarn is collected in the form of a bobbin on a yarn carrier of separate hollow spindles, wherein the separate hollow spindles are positioned atop one another. With formation of a yarn balloon the spun yarn is withdrawn from the bobbins and guided through the hollow spindle axle of the respective hollow spindle. The spun yarn withdrawn from the upper one of the hollow spindles is guided through the hollow spindle axle of the lower one of the hollow spindles. Both spun yarns are then guided together to a winding device positioned below the lower one of the hollow spindles. The hollow spindles are rotated as a function of the winding speed of the winding device such that a twist of the spun fibers is at least partially canceled.
